Code:
Hud.RunOnPlugin<PlayerBottomBuffListPlugin>(plugin =>
{
plugin.BuffPainter.ShowTimeLeftNumbers = true;
plugin.RuleCalculator.Rules.Add(new BuffRule(134872) { IconIndex = 5, MinimumIconCount = 1, ShowStacks = true, ShowTimeLeft = true }); // Old stacks, from a previous archon
plugin.RuleCalculator.Rules.Add(new BuffRule(134872) { IconIndex = 2, MinimumIconCount = 1, ShowStacks = true }); // Stacks of the current archon
plugin.RuleCalculator.Rules.Add(new BuffRule(440235) { IconIndex = 0, MinimumIconCount = 1, ShowStacks = true }); // Chantodo Stacks
} );
TH already shows the skill bar for your own character and the cooldowns of the skills. Just to see Archon's cooldown would not install that plugin
If you want to see the remaining buff times, I would also install TimeleftSkillBar ([V9.1] [INTERNATIONAL] [RNN] TimeLeftSkillBar)
